Main Application Scenarios of a 5G Mobile Communication System

With people's pursuit of speed, latency, high-speed mobility and energyefficiency, and diversity and complexity of services in future life, the3rd Generation Partnership Project (3GPP) international standardsorganization has begun to develop 5G. Main application scenarios of 5Gare enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-LatencyCommunications (URLLC), and massive Machine-Type Communications (mMTC).The main application scenarios of the 5G mobile communication system aredescribed below.

1) eMBB scenario: a target of the eMBB is to allow a user to obtainmultimedia content, service and data, and requirements of services ofeMBB are growing very rapidly. Since eMBB may be deployed in differentscenarios, such as indoor, urban area, rural area, etc., servicecapabilities and requirements of eMBB vary greatly. Therefore, theservice must be analyzed in combination with specific deploymentscenarios.

2) URLLC scenario: typical applications of the URLLC include: industrialautomation, power automation, telemedicine operations, traffic safetyassurance, etc.

3) mMTC scenario: typical characteristics of the mMTC include: highconnection density, small data volume, latency-insensitive service,low-cost module, long service life, etc.

Three Radio Resource Control (RRC) States in 5G Network Environment

In the 5G network environment, in order to reduce air interfacesignaling, restore wireless connection quickly and restore data servicequickly, a new RRC state, that is, an RRC inactive (RRC_INACTIVE) stateis defined. This state is different from an RRC idle (RRC_IDLE) stateand an RRC connected (RRC_CONNECTED) state. The three RRC states in the5G network environment are described below.

1) RRC_IDLE state: mobility is UE-based cell selection and reselection,paging is initiated by a Core Network (CN), and paging area isconfigured by the CN. There is no UE Access Stratum (AS) context at abase station. There is no RRC connection.

2) RRC_CONNECTED state: there is an RRC connection, and there is UE AScontext at the base station and UE. The network side knows that alocation of UE is of a specific cell level. Mobility is the mobilitycontrolled by the network side. Unicast data may be transmitted betweenUE and the base station.

3) RRC_INACTIVE state: mobility is UE-based cell selection andreselection. There is connection between CN and Radio Access Network(RAN), the UE AS context exists on a certain base station, paging istriggered by RAN, RAN-based paging area is managed by RAN, and thenetwork side knows that the location of UE is based on a paging arealevel of RAN.

CA Technology

In order to meet high-speed requirements, CA technology is alsosupported in 5G. CA refers to jointly schedule and use resources onmultiple Component Carriers (CCs), so that NR system may support alarger bandwidth and thus may achieve a higher system peak rate.According to a continuity of aggregated carriers on a spectrum, the CAmay be divided into continuous carrier aggregation and discontinuouscarrier aggregation. According to whether bands in which the aggregatedcarriers are located are the same, the CA may be divided into Intra-bandcarrier aggregation and Inter-band carrier aggregation.

Primary Cell Component (PCC) is referred to as primary carrier, there isone and only one PCC, and PCC provides an RRC signaling connection, NASfunction, security, etc. Secondary Cell Component (SCC) is referred toas secondary carrier, and SCC only provides additional radio resources.

LTE Release 15 (R15) optimizes the CA, and mainly optimized functionsare as follows.

UE measurements during IDLE mode: measurement configuration during theidle mode may be configured in an RRC release message, and themeasurement configuration during the idle mode may also be configured bysystem broadcast SIB5. When there is a dedicated configuration, thededicated configuration is used, otherwise the measurement configurationin SIB5 is used. There is no effective time limit to idle measurementconfiguration in SIB5. The idle measurement configuration configured indedicated signaling also is configured with the effective timeconfiguration, that is, T331. When T331 times out or stops, the idlemeasurement configuration configured in the dedicated signaling isreleased. Whether UE continues to use the idle measurement configurationin SIB5 depends on the UE. After obtaining the measurement configurationduring the idle mode, the UE performs measurement, indicates a presenceof an idle measurement result to the network side in an Uplink (UL)message, and then reports it based on a request mode of the basestation. A cell will also broadcast in SIB2 whether reporting of theidle measurement result is supported.

DC Technology

During early deployment of the NR, it is difficult to obtain complete NRcoverage, thus the typical network coverage is wide area LTE coverageand NR island coverage mode. Moreover, a large amount of LTE servicesare deployed below 6 GHz, and there is very little frequency spectrumbelow 6 GHz to be used by 5G. Thus, NR must study an application offrequency spectrum above 6 GHz, but the high frequency band has limitedcoverage and fast signal fading. At the same time, in order to protectmobile operators' early investment in LTE, an operating mode of tightinterworking between LTE and NR has been proposed.

In order to achieve 5G network deployment and commercial applications assoon as possible, 3GPP first completed a first 5G version, namelyE-UTRA-NR Dual Connectivity (EN-DC). In EN-DC, an LTE base station (eNB)serves as a Master Node (MN), and an NR base station (gNB or en-gNB)serves as a Secondary Node (SN). The network deployment and networkingarchitecture of the EN-DC is shown in FIG. 2 . E-UTRAN represents a partof an access network, and EPC represents a part of a core network. Thepart of the access network consists of at least one eNB (two eNBs areshown in FIG. 2 ) and at least one en-gNB (two en-gNBs are shown in FIG.2 ), herein the eNB serves as a MN, the en-gNB serves as an SN, and boththe MN and SN are connected to the EPC.

In the later stage of R15, other DC modes, that is, NR-E-UTRA (NE)-DC,5G Core Network (5GC)-EN-DC, NR DC, will be supported. For the EN-DC,the core network connected to the access network is EPC, while for theother DC modes, the core network connected to the access network is 5GC.

UE Capability Support

In the project of CA/DC enhancement in Release 16 (R16), correspondingmeasurement is configured for UE in an idle state or an inactive state,and then the UE reports a measurement result to the network side whenentering a connected state, to assist the network side in configuring CAor Multi-RAT (MR)-DC.

In LTE CA, UE measures in an LTE idle mode and reports a measurementresult to a network side to assist the network side in configuringfunction (or capability) of CA. The UE will report UE capabilityindication information to indicate to the network side whether UEsupports the function (or capability). With reference to Table 1,ca-IdleModeMeasurements is the UE capability indication information, andwhen it is set to be supported, it means that the UE supports thefunction (or capability).

Moreover, UE may also report UE capability indication information forindicating whether the UE supports EN-DC. With reference to Table 2,en-DC is the UE capability indication information, and when it is set tobe supported, it means that the UE supports the function (orcapability).

Moreover, UE may also report UE capability indication information forindicating whether the UE supports NE-DC. With reference to Table 3,ne-DC is the UE capability indication information, and when it is set tobe supported, it means that the UE supports the function (orcapability).

In the project of CA-DC enhancement in NR, LTE also needs to extend tosupport measurement for an NR frequency layer, to support requirement ofrapidly configuring EN-DC. On the other hand, an E-UTRAN frequency layerand an NR frequency layer need to be configured in the NR to supportrequirements of configuring NR CA and MR-DC (NE-DC, NR-DC). In order toclarify the capability of the UE about support or nonsupport for themeasurement for an NR frequency layer in the LTE and support ornonsupport for the measurements for the E-UTRAN frequency layer and theNR frequency layer in the NR, the following technical solutionsaccording to the embodiments of the disclosure are proposed.

FIG. 3 is a schematic flowchart of a method for determining capabilityof a terminal according to an embodiment of the disclosure. As shown inFIG. 3 , the method for determining capability of a terminal includesthe following operation.

At block 301, the terminal sends at least one piece of capabilityindication information to a network. The at least one piece ofcapability indication information indicates whether the terminalsupports measurement for at least one of a first frequency layer or asecond frequency layer and reporting of a measurement result.

In the embodiment of the disclosure, the terminal may be any devicecapable of communicating with the network, such as a mobile phone, atablet computer, a notebook computer, an in-vehicle terminal and thelike.

In the embodiment of the disclosure, the description about the networkmay also be replaced with a network device. In an example, the networkis an access network, and correspondingly, the network device is anaccess network device (such as a base station).

In an implementation of the disclosure, the first frequency layer is anE-UTRAN frequency layer, and the second frequency layer is an NRfrequency layer.

In the embodiment of the disclosure, the terminal sends the at least onepiece of capability indication information to the network, and the atleast one piece of capability indication information is used for jointlyindicating whether the terminal supports the measurement for at leastone of the first frequency layer or the second frequency layer andreporting of the measurement result. This is described below incombination with different application scenarios separately.

First Application Scenario

The network is a Long Term Evolution (LTE) access network, and the atleast one piece of capability indication information includes firstcapability indication information, second capability indicationinformation and third capability indication information.

The first capability indication information indicates that the terminalsupports a first measurement in an LTE idle state and reporting of ameasurement result. The first measurement refers to a measurementperformed to assist the network side in configuring Carrier Aggregation(CA).

The second capability indication information indicates that the terminalsupports EN-DC.

The third capability indication information indicates that the terminalsupports NR.

For example, the terminal reports the first capability indicationinformation, the second capability indication information and the thirdcapability indication information to the LTE access network. The firstcapability indication information is the ca-IdleModeMeasurements. Withreference to the above Table 1, when the ca-IdleModeMeasurements is setto be supported, it means that the terminal supports the correspondingfunction (or capability). The second capability indication informationis the en-DC. With reference to the above Table 2, when the en-DC is setto be supported, it means that the terminal supports the correspondingfunction (or capability).

Based on the above scenario, the at least one piece of capabilityindication information indicates that the terminal supports measurementfor an NR frequency layer and reporting of a measurement result. Thisavoids reporting of additional capability indication information fromthe terminal to the network, and saves signaling overhead.

Further, in an optional implementation of the disclosure, the at leastone piece of capability indication information includes, in addition tothe above first capability indication information, second capabilityindication information and third capability indication information,fifth capability indication information for indicating that the terminalsupports an inactive state. In this scenario, the at least one piece ofcapability indication information indicates that the terminal supportsperforming measurement for at least one of an E-UTRAN frequency layer oran NR frequency layer in the inactive state and reporting of ameasurement result.

The network is a Long Term Evolution (LTE) access network, and the atleast one piece of capability indication information includes fourthcapability indication information for indicating that a version of theterminal is a terminal involved in R16 or later, or indicating that theterminal supports at least one of CA or DC enhancement.

For example, the terminal reports the fourth capability indicationinformation to the LTE access network.

Based on the above scenario, the at least one piece of capabilityindication information indicates that the terminal supports measurementfor an NR frequency layer and reporting of a measurement result.

Further, in an optional implementation of the disclosure, the at leastone piece of capability indication information includes, in addition tothe above fourth capability indication information, fifth capabilityindication information for indicating that the terminal supports aninactive state. In this scenario, the at least one piece of capabilityindication information indicates that the terminal supports performingmeasurement for at least one of an E-UTRAN frequency layer or an NRfrequency layer in the inactive state and reporting of a measurementresult.

Third Application Scenario

The network is an NR access network, and the at least one piece ofcapability indication information includes sixth capability indicationinformation for indicating that the terminal supports early measurementin the NR and reporting of a measurement result.

For example, the terminal reports the sixth capability indicationinformation to the NR access network. The early measurement andreporting of the measurement result means that after performing themeasurement according to a measurement configuration, the terminalreports a corresponding measurement result to the network after enteringan active state.

In an implementation, the sixth capability indication information iscarried in an NR capability container. Specifically, a new capabilityindication information (that is, the sixth capability indicationinformation) is defined in the NR capability container, and thecapability indication information indicates that the terminal supportsthe early measurement in the NR and reporting of the measurement result.

Based on the above scenario, the at least one piece of capabilityindication information may have the following two indication modes.

Further, in an optional implementation of the disclosure, the at leastone piece of capability indication information includes, in addition tothe above sixth capability indication information, seventh capabilityindication information for indicating that the terminal supports NE-DC.The seventh capability indication information is the ne-DC. Withreference to the above Table 3, when the en-DC is set to be supported,it means that the terminal supports the corresponding function (orcapability). In this scenario, the at least one piece of capabilityindication information indicates that the terminal supports measurementfor an E-UTRAN frequency layer and reporting of a measurement result.Further, the at least one piece of capability indication information mayfurther indicate that the terminal supports the measurements for theE-UTRAN frequency layer and the NR frequency layer in the LTE andreporting of the measurement results.

2) The at least one piece of capability indication information indicatesthat the terminal supports the measurements for the E-UTRAN frequencylayer and the NR frequency layer and reporting of the measurementresults.

Further, the at least one piece of capability indication information mayfurther indicate that the terminal supports the measurements for theE-UTRAN frequency layer and the NR frequency layer in the LTE andreporting of the measurement results.

Fourth Application Scenario

The network is an NR access network, and the at least one piece ofcapability indication information includes first capability indicationinformation for indicating that the terminal supports a firstmeasurement in an LTE idle state and reporting of a measurement result.The first measurement refers to a measurement performed to assist anetwork side in configuring CA.

For example, the terminal reports the first capability indicationinformation to the NR access network. The first capability indicationinformation is the ca-IdleModeMeasurements, and with reference to theabove Table 1, when the ca-IdleModeMeasurements is set to be supported,it means that the terminal supports the corresponding function (orcapability).

In an implementation, the first capability indication information iscarried in an LTE capability container, that is, the terminal setsca-IdleModeMeasurements to be supported in LTE capability.

In another implementation, the first capability indication informationis carried in an NR capability container, that is, the terminalindicates in NR capability that ca-IdleModeMeasurements in the LTE isset to be supported.

Based on the above scenario, the at least one piece of capabilityindication information indicates that the terminal supports measurementsfor an E-UTRAN frequency layer and an NR frequency layer in the NR andreporting of measurement results.

Thesecond measurement refers to a measurement performed for DC quickconfiguration.

For example, the terminal reports the eighth capability indicationinformation to the LTE access network or the NR access network.

1) When the eighth capability indication information indicates that theterminal supports the second measurement and reporting of themeasurement result, the at least one piece of capability indicationinformation indicates that the terminal supports measurements for anE-UTRAN frequency layer and an NR frequency layer and reporting ofmeasurement results.

Herein, whether the terminal resides in the LTE access network or the NRaccess network, the terminal supports the measurements for the E-UTRANfrequency layer and the NR frequency layer and reporting of themeasurement results.

Further, in an optional implementation of the disclosure, the at leastone piece of capability indication information includes, in addition tothe above eighth capability indication information, ninth capabilityindication information for indicating that the terminal supports an LTEinactive state. In this scenario, the at least one piece of capabilityindication information indicates that, when the terminal resides in theLTE access network, the terminal supports measurements for the E-UTRANfrequency layer and the NR frequency layer in the inactive state andreporting of measurement results.

Herein, whether the terminal resides in the LTE access network or the NRaccess network, the terminal does not support the measurements for theE-UTRAN frequency layer and the NR frequency layer and reporting of themeasurement results.

3) When the eighth capability indication information indicates that theterminal does not support the second measurement and reporting of themeasurement result, the at least one piece of capability indicationinformation further includes tenth capability indication information forindicating whether the terminal supports measurement for an NR frequencylayer while residing in the NR access network and reporting of ameasurement result.

According to the technical solutions in the embodiments of thedisclosure, as to the capability of the terminal about support ornonsupport for the measurement for at least one of the first frequencylayer or the second frequency layer and reporting of the measurementresult, the method for indicating the capability is defined clearly,that is, whether the terminal supports the measurement for at least oneof the first frequency layer or the second frequency layer and reportingof the measurement result are indicated by using at least one piece ofcapability indication information, which may avoid reporting ofadditional capability indication information and achieve the purpose ofsaving signaling.
